Full suspension of tractors refers to the suspension of the driver and vehicle. While some tractor manufacturers already speak of full suspension when the front axle and the cab are suspended, other manufacturers (e.g. JCB or John Deere ) understand full suspension to mean the specific vibration decoupling of both axles from the rest of the vehicle by means of a sprung and damped suspension.

With the “Deutzer Trekker” there was already a tractor with sprung front and rear axles in 1919. The concept with two sprung axles could not prevail, mainly for cost reasons.

It was only since the introduction of hydropneumatic suspension in tractor suspensions , which enabled the suspension to be locked, that this suspension principle was rediscovered. The only full suspension tractors on the market in 2004 were JCB's Fastrac and John Deere's 8020. Other manufacturers followed later.

The advantage of the full suspension of tractors is that the vibrations are reduced as close as possible to where they originate, so that there is no separate need to reduce vibrations on the driver, vehicle and attachment. The high costs of such systems are disadvantageous.
